When the detected signal exceeds the preset pressure, the signal is sent into the other outer apparatus through the lead-wire part 26. The controller 24 is not always required. When a plurality of the detectors are used, there are not much troubles even if a plurality of the controllers are not provided. Sometimes, the detectors must be simplified. Therefore, the controller can be attached and removed as required, and the general application property can be improved.

Patent JP-H09182068-A (JP)
Title: Image transmission method
Inventor: HIRATA SHINICHI
IPC: H04N19/46
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To improve the image transmission efficiency by dividing an original image so as to have these divided images similar to each other, transmitting the divided images after encoding them and giving interpolation to the wrong group via the corresponding part of another similar divided image if an error is detected in a received image. SOLUTION: An image conversion part 10 rearranges an original image to be inputted into plural images of high correlation on every pixel line. Then an encoding part 2 compresses and encodes the converted image data by an H. 261 encoding system or an MPEG1 system and builds the encoded image data into a transmission packet in every encoding unit GOB(group of block) to sends them to a transmission line 4 with addition of an error detection code. When an error is detected at the receiving side via an error detection part 12, an error interpolation part 13 performs the interpolation of the error by copying a normally received corresponding part from a divided image other than that having a wrong part. Then an image inverse conversion part 11 reconfigurates the divided images and outputs them.  Thus a transmission error is easily interpolated with high precision and the accuracy of the reconfigurated images can be improved.

Abstract: PURPOSE:To easily detect abnormality of liquid viscosity by applying a centrifugal force to the liquid charged in a transparent container, detecting the liquid surface deformation of the liquid by a sensor, and measuring the time up to when the output voltage of the sensor reaches a specific value. CONSTITUTION:A liquid containing container 1 is put in a container holder 2 and a photoelectric sensor 4 for level detection and a transmitted light quantity sensor 5 are arranged on a sensor holding plate 7. A motor 8 is started to elevate a support lever 6 and the liquid level 13 in the container 1 is aligned with the position of the sensor 4. Then a motor 3 is started to rotate the holder 2 (at 300 - 1,500r.p.m.) and then rotate the container 1, and then the liquid surface 13 deforms in a concave arcuate shape 13a. The light which is emitted by a projector 5a passes through the liquid and reaches a photodetector 5b. Its quantity of photodetection is converted by an AD conversion board 10 into a voltage and a personal computer 11 records the necessary time up to when the output voltage of the sensor 5 reaches the specific output voltage and the output voltage of the sensor which is a specific time after the start of rotation of the container 1. The time and voltage have constant relation as to the viscosity variation of liquid food, so abnormal viscosity is detected.
